Design a wireless call bell system that feeds into 1-3 light bar stations.
System is for a 27+ factory machines so operators can flip a WIRELESS/RADIO switch at the machine and a light will go on on light bars allowing the supervisor or technician to know that the operator is having a problem at a specific machine.
This design should use common, inexpensive stock components, readily available for purchase online. The simpler or dumber the system the better. I really just want on/off wireless switches which can trigger relays for lights wirelessly.
We have a variety of power available on the injection molding machines. Our shop spans some 30,000 square feet.
We can fabricate and build system given design.
